About the Compressor
Shrink images and PDF documents for web publishing, email attachments, and portal uploads. Images are re-encoded with the browser's Canvas API and PDFs are optimized with pdf-lib — all on your device.
Choose a preset such as Balanced, Smaller file, or Print ready, then compare the original and compressed size before downloading. Savings depend on the file: photos usually compress well, while already-optimized files may shrink less.

Frequently asked questions
Will compression reduce quality?
Stronger presets trade some quality for a smaller size. Print ready keeps quality highest.
Are my files uploaded to compress them?
No. Compression runs locally in your browser.
Why did my file barely shrink?
Files that are already optimized have little left to remove.
